RO110 is 110MW engine. That's too big even for carriers, unless you want to use only two of the engines but you lose the element of redundancy.

What I'm looking for information is QD400.

This is a 40MW+ engine that can be used to potentially power an 80,000 ton carrier with four of these engines.

Can we have some pictures of these Gas Turbines ? Especially those developed by AVIC?

Taken directly from the horse's mouth.

RO110 -- 110MW. This engine isn't new. Its been around for a few years now. When this engine appeared, there was buzz it would be used with a future aircraft carrier. The answer should be, no, this is pure stationary power generation only.

This table is very important. It confirms the existence of two engines more powerful than the QD280, which is the engine used on the Type 052C, 052D and the Type 055. QD300 could be the engine coming for future destroyers, whether its a new variant of the 052X series, or a new 055 variant. QD500 is also very important. The only possible use I can think for this is for an aircraft carriers, with four of these 50MW gas turbines producing a total of 200MW, which is about the total power produced by the Nimitz class or a Kitty Hawk class carrier.

Smaller engines like QD50 to QD128 might be used for smaller warships, e.g. future corvettes and frigates. Commercial ship applications in China is heavily biased and reliant towards diesel use from the smallest to the biggest ships, so I am inclined to think if you see a naval or marine gas turbine, it might be for military use. Small gas turbines can also be used for small power plant applications.

QD280 producing 30MW. They probably redesignated this QD280 version to QD300.

QD128 might be the engine used for a future corvette or frigate.

Thanks @Tam for the image of QD128.
I have already seen (and posted) the pics of QC280 and R0110 Gas Turbines. (Harbin GT establishments products).But I have not been successful in finding the pics of AVIC products.
I have some doubts -
Is it QC280 or QD 280 ? ( What is the expansion of the QC or QD terms? )
Is it R0110 or RO110 ?

You don't call it AVIC anymore. AVIC and COMAC combined and invested as stock and shareholders for a new umbrella company that puts most of China's engine makers into one banner: AECC or Aviation Engine Company of China.

QC is dropped for QD. It is RO not R0.

So here on, domestic engines are AECC.

Pardon guys to interrupt, but this topic is for jet-engines in the Air Force section and not for each and every gas turbine or naval powerplant!

Shall I move this part into the naval section or am I misunderstanding the post and missed the PLAAF relevance?

Isn't the chinese Institute 703 in charge of this. Why do they need this Technology transfer agreement in the first place if they have achieved self sufficiency and competitiveness with R0110 ?
I think this transfer was important to China.
I'd like to know much more about this. Btw,

explains in detail the exact necessity for procuring the H-25 technology.
No,R0110 is a project of AVIC but now AECC from the first day

Power station GT is a big market,and CSOC wants to get some share from it, also AECC.
But the big players are not them. Shanghai Electric Group Can produce F class GT in fully indigenous way, and H class in assembling way.

I have translated it (google translate )



Basically, don't expect WS-20 to be equipped in numbers aboard any Y-20 soon enough (as there are testing requirements yet to be met)
The same for CJ-1000A engines.
Edit: read and infer what you can. :rolleyes:
